Hillary Clinton blasted the "state's neglect" for the ongoing water crisis in Flint, Michigan, during an emotional visit today to an African-American church in the city.

"We don't yet know how many children have been affected by lead poisoning, we don't yet know how many challenges they will face," she said from the pulpit of Flint's House of Prayers. "What we do know we know is that even a single child suffering lead poisoning due to the state's neglect is one child too many."

Clinton, who took a break from campaigning in New Hampshire to visit Flint, is the first presidential candidate to visit the city.

During her remarks today, she called the situation in Flint "immoral" and said that if a situation like this had happened in a wealthier community, "I think we all know we would have had a solution yesterday."

She called for Congress to approve a $600 million amendment to help the city.

Clinton has recently made the crisis in Flint a top issue of her campaign. Two of her aides traveled to the city last month to address the crisis. During her visit today, Clinton was also scheduled to meet with Flint Mayor Karen Weaver and other city officials.
